Bo it known that I, ERNEST AM. WILSON,

i aycit'izen of the `UnitedStates ofAmerioa, f and a resident of the city ofSeattle, in the conntyfof King and State of `W,ashington, have invented certain new and .useful Im' proveniente in Headlight Screens `and Regulators, of which theI following a specil ication. i l flo, invention relates to `screens intended e `fory"partially.or Whol1ymaskingthe.1n-

While the device is equallv applicable to head lights which are otherwise employed, I will describe the same as applied. to auto Patenten Mair. 2i, i916.

mobiles, its use upon other head lights bedingte understood as being included therein.

yHead lights of the character referred to are usually round in shape; I therefore providewa frame 1which is of the same shape and adapted to fit closely Within the forward part of the head light casing. In this ring-like frame 1, are mounted a series of screen bars 2 and 20, these being essentially alike, but arranged as separate and independently movable sets. The set 2 extends across the upper portion of the head light opemng, While the set 20 extends across the dently the screen. 'might hedivided into more than two sets, if there werefany reason for this.- y f .The material preferred for making these screen bars is glass. '[hese may be of plain clear glass, 4or the glass lmay be frosted, colored, or provided.,'1.1pon one surface with either a screening coating v'which will interlower halfof the head light opening. Evicept part or all of the light, or of a coating..

which is ofv a reflecting character, as silvering.' Each end of each screen bar is secured Within a pivoted member 22, `which embracesthe end ofthe bar and Whichlhas 'a journal 23, adapted to enter the holeformed in the frame 1, or in lugslO'ivhich arel se'-4 whereby all the bars of 'eachn set are caused to move together and to occupy-likevangular The two controllingbars 3, of

32, which `tends to' draw them together, ror

'curedto said-frame.` The screen bars of j 'each set are connected by means of rods 3 which, in the form `of construction shown, vhave olf-set arms 30, Whichy pivotallfj engagewith lugs 31, secured to the screen bars,

into the position' hho'wn in Figs.v 1 and 2. in i 'which thescreen hars extend substantially parallel with'the directmn of the fproiected light rays;4 While I have shown all-of these hars as being parallel with eachother in this position, itf-'isl evident that their-pal.l y'

allelism may be variedy to whatever extent nelly'` of the casing, With a-crank arm 25,

whereby the screen bars may be operated to turn them upon their pivots. These crank arms, lin the arrangement ofv parts as herein shown, project each toward the other, Whereby, when operated loy a pulldirected toward the rear of thehead light, the screen bars Will be' turned in` one direction for one set and in the opposite direction for the other set,l that is, one set will be turned right handly, and the other set left handly.

' The voperating cords, or Wires 4 and 40, are each connected with its respective crank arm 25, and are extended aboutv guide pulleys 4l, whichA are suiiicient in number and so located' as to carry these'cords or'wires,

, to the position vfrom which it is desired to control the head light. This position, for

an automobile, Would be the controlling wheel thereof. y

I'have shown the screen bars as having their edges 21 beveled, so that when in theV requiredposition, as is shown in Fig. 4, the

' edges entirely overlap, thus forming a complete screen, which screen will entirely shut out the light, if the screen bars are made opaque.- This Vis true oi all of the `screen bars excepting the edges which are outer- ,most in each set, as for instance, the upper edge of the uppermost bar, the lower edge of the lowermost bar, and the edges of the bars of the -two sets which meet'. These latter bars, being the lowermost bar ot lthe upper set and the uppermost bars 'of the lower set, turn in opposite directions and, as it is desired that the two sets be capable of inde# pendent movement, their meeting edgesfare .made substantially Asquare across. 4

By ldividing the screen bars intwo`or more sets, it is possible to screen Aa part of the headlight, leaving the other partsun-v screened. ln thisI way the, upper halt of the projected rays'may be cut ofi'v while the other half is left in its normal brilliancy. y.

Stops 26 are provided which engage the operating crank arms v25, to llimit their movement in cach direction. that the edges ot' these screen rbars shall never `come in actual contact withA each other, as, being madel o't glass the shock of Contact would be liable to chip their edges.

crank arms'to a controlling point'.

3. A headlight screen comprising a frame adapted rto be fitted to the headlight casing4 shutters or screen bars pivoted in said frame, a plurality of controlling bars each connected. with its respective screenvbars to cause them to swing together, one screen bar -of each set having its pivot journal extending through the frame and the light. casing and actuating meansconnecting each of said projecting journals with a distant point.

4. A headlight screen comprising a frame adapted to encircle the emitted rays, screen -controlling bars, each connected with its respectivescreen bars to maintain them in like angular position, a yspring connected to each of said controlling bars to thereby turn the screen bars into positions of approximate parallelism with the emitted rays, and means sition to said spring.
